Jeff Bezos stepped back into the startup arena as co‑CEO of Prometheus, a venture targeting “physical AI.” The company, founded with Vik Bajaj, just closed a $12 billion financing round, doubling last year’s $6.2 billion and pushing its valuation to $41 billion. Investors include JPMorgan Chase, Goldman Sachs, BlackRock and Bezos himself, while the staff count sits at roughly 150.

Bezos told CNBC the bulk of the capital will fund massive compute clusters, a necessity for training models that translate deep‑learning advances into robotics and manufacturing. He described the ambition as building an “artificial general engineer,” a toolset designed to compress the invention cycle that historically powered wealth—from the plow to the steam engine.

With 150 engineers already on staff, Prometheus aims to deliver a platform that automates design, testing and production, promising manufacturers faster iteration and lower R&D spend. If the compute budget translates into usable tools, the company could reshape how hardware is conceived, narrowing the gap between software breakthroughs and physical products.

The $12 billion injection signals Wall Street’s confidence that AI will soon leave the cloud and move into factories. By betting on a universal engineering assistant, Prometheus positions itself against niche robotics firms and large cloud providers alike, forcing the industry to consider whether massive compute spend can truly accelerate hardware innovation at scale.
